tym·pan·ic nerve

[TA]
a nerve from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus that supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibers also pass through the tympanic nerve via the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibers that continue to supply the parotid gland.

tympanic nerve

a branch of the glossopharyngeal nerve that participates in the formation of the tympanic plexus and provides sensory innervation within the middle ear to the mucosa of the cavity, pharyngotympanic tube, and mastoid air cells. It also contributes general visceral efferent fibers, which leave the tympanic plexus in the lesser petrosal nerve.

tym·pan·ic nerve

(tim-pan'ik nĕrv) [TA]
Origin, from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus that supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibers also pass through the tympanic nerve through the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibers that continue to supply the parotid gland.
Synonym(s): nervus tympanicus [TA] , Andersch nerve.

Andersch,

Carolus Samuel, German anatomist, 1732-1777.
Andersch ganglion - the lower of two sensory ganglions on the glossopharyngeal nerve as it traverses the jugular foramen. Synonym(s): inferior ganglion of glossopharyngeal nerve
Andersch nerve - Synonym(s): tympanic nerve

Jacobson,

Ludwig L., Danish anatomist, 1783-1843.
Jacobson anastomosis - a portion of the tympanic plexus.
Jacobson canal - a minute canal in the wedge of bone separating the jugular canal and carotid canal. Synonym(s): tympanic canaliculus
Jacobson cartilage - a narrow strip of cartilage located between the lower edge of the cartilage of the nasal septum and the vomer. Synonym(s): cartilago vomeronasalis
Jacobson nerve - Synonym(s): tympanic nerve
Jacobson organ - a fine vestigial horizontal canal ending in a blind pouch in the mucous membrane of the nasal septum. Synonym(s): vomeronasal organ
Jacobson plexus - a plexus on the promontory of the labyrinthine wall of the tympanic cavity, formed by the tympanic nerve, an anastomotic branch of the facial nerve, and sympathetic branches from the internal carotid plexus. Synonym(s): tympanic plexus
Jacobson reflex - flexion of the fingers elicited by tapping the flexor tendons over the wrist joint or the lower end of the radius.

tympanic

1. of or pertaining to the tympanum.
2. bell-like; resonant.

tympanic cavity
middle ear.
tympanic membrane
a thin, semitransparent membrane, nearly oval in shape, that stretches across the ear canal separating the middle ear from the external acoustic meatus (outer ear); called also the eardrum. It is composed of fibrous tissue, covered with skin on the outside and mucous membrane on the inside. It is constructed so that it can vibrate freely with audible sound waves that travel inward from outside. The manubrium (handle) of the malleus (hammer) of the middle ear is attached to the center of the tympanic membrane and receives the vibrations collected by the membrane, transmitting them to other bones of the middle ear (the incus and stapes) and eventually to the fluid of the inner ear.
